LAMP.

Specification of Letters Patent No. 30,877, dated October 9, 1860.

my invention. Fig. 2 a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the two figures.

The object of this invention is to obtain a lamp for burning lard, grease collected in cooking etc.

The invention is designed solely for domestic or household use in rural districts and to apply the majority of scraps and grease for illuminating purposes which are now used less advantageously.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents the base or lower part of the lamp which may be of cylindrical form and which has within a smaller cylinder B, secured centrally and permanently in any proper way. vertically its whole length as shown at a, and within the cylinder B. a hollow or tubular screw C, is placed the lower end of which has a projecting rod Z) attached, which rod projects through the slot (4, and prevents the screw from turning-as will be fully understood by referring to Fig. 1.

On the upper end of the base A, there is placed a cap D, which is allowed to turn freely on the base and to this cap there is attached a vertical tube E, which is the fountain or body of the lamp which contains the burning material. The tube E, is in line with the cylinder B, and the lower end of the former projects down a short distance within the latter and has two projections 0, 0, between which the thread cl, of the screw is fitted, see Fig. 1. O11 the upper end of the screw C, there is a piston F,

The cylinder B, is slotted which fits snugly within the tube E, and has a small hole 6, made through it to admit of a straw G, being passed through it..

Around this straw G, a piece of cotton twist H, is wound, the twist extending down to the piston F. The straw and twist extend a short distance above the top of the tube E.

The base A, cylinder B, and tube E, may be constructed of sheet metal, and the screw C, may be of the same material the thread (I, being formed by a wire soldered to a tube. I do not however confine myself to any particular material. The lower part of the base A is perforated as shown at f.

The operation of the lamp is as follows: The lard or other grease to be burned is placed in the tube E, the piston F, being at the bottom of the tube, the straw G, with the cotton twist H, around it being previously inserted in tube E. The cotton twist H, is then ignited and the flame is supplied with air which passes up through the straw G, the air passing through the perforations f, in the base A, through the slot (4, upward in the bottom screw C, and thence into the straw G, as indicated by the red arrows. As the lard or grease in E. is consumed, the piston F, is raised by turning the tube E, the project-ions c, (1, raising and lowering the screw C. By this arrangement the lard or grease is kept at the top of the tube E, near the flame and in a proper fluid state until the whole is consumed.

The wick may be snuffed in the ordinary way as the straw G, will burn as readily as the cotton twist.

The whole device is extremely simple and may be constructed at a moderate cost.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,

The tube E, and piston F, the latter being adjusted by the screw C, or other device, in combination with a. hollow wick formed of a straw G, or its equivalentand twist H, essentially as and for the purpose set forth.
